There are four seasons in a year, my favorite is summer.

Summer usually starts in April every year. Unlike spring, the weather is hot and muggy, this is also the hottest season of the year. The annual temperature from 28 degrees to 38, in the hottest time, the temperature up to 40 degrees and more. Summer weather is very convenient to plant growth. They have a chance to receive and absorb more sunlight, so plants are greener. That is also the reason why summer has so many delicious fruits. In the summer, we can absorb a lot of Vitamin D from the sun, but the afternoon sun will darken the skin.

Talking about summer, it is impossible not to mention outdoor activities. Many tourist and leisure activities are held in the summer. People tend to go to the beach. In the summer, my friends and I often fly kites and bathe in the river together.

Summer brings everyone joy, comfort, time with family after hard times. Therefore, this is the favorite season of many people.
